Default Tried assembling my own crossover...why didn't it work?

This was my first attempt. Its a MTM design for a center channel so I thought I'd be fairly simple after reading the tutorial on partsexpress and having the how-to off Solens website. I put everything together before soldering it just to see if it'd work, but only the tweeter worked. I couldn't get any sound from the mid/woofers. I took it all apart and started from scratch, assembling only the mid section. Still, no sound. What could POSSIBLY be the problem? I know my description is very vague, but I'm pretty sure I assembled it correctly. Is it easy to break a component in the crossover? Could I have broken something? I'm just asking you guys if you can give me a couple options to check out...what do you guys think?

I don't think you broke anything in the crossover, it will be likely the connections.

Testing is easier with a woofer as you are less likely to damage them.
Make sure:
-There is power coming into the circuit
-You don't have some sort of short putting the amp into protect
-Test the circuit out with a multimeter making sure all the connections are there that should be and none that aren't

Inductors have wire varnish on them. Have u scraped it off? Take a multi miter and just test voltage from one connection to another. Itís usually something very simple.

Do the mids by any chance have dual voice coils?

Thanks very much for the advice! I got a little frustrated and ended up taking it to a local electronics store. The same guy assembled the crossover in my front speakers and did a nice clean job. I'll might as well get it done right!

Thanks again!
